Compact microstrip balanced phase shifter with common-mode suppression
2020 IEEE Asia-Pacific Microwave Conference (APMC), 2020Balanced phase shifter (BPS) plays an important role in differential beamforming networks and phased array antenna systems due to the capabilities of differential-mode (DM) phase shift and common-mode (CM) suppression. The compactness of BPS also becomes highly demand for its benefit to miniaturize the system.

A 100‐GHz full 360° reflection‐type phase shifter using a balanced phase inverter
Microwave and Optical Technology Letters, 2020AbstractThis paper presents a 100‐GHz phase shifter capable of providing full 360° continuous phase tuning range in 55 nm CMOS technology. The phase shifter is based on reflection‐type phase shifter (RTPS), which has more than 180° phase shift and employs a 0°/180° phase inverter (PI).

An I/Q active balanced harmonic mixer with IM2 cancelers and a 45° phase shifter
IEEE Journal of Solid-State Circuits, 1998To reduce DC offset caused by local-oscillator-signal self-mixing in a direct-conversion receiver, an active balanced harmonic mixer with second-order intermodulation (IM2) canceler was proposed, and a direct downconverter containing the mixer and a 45/spl deg/ phase shifter was fabricated on a BiCMOS chip.

Balanced detection for spectral-domain optical coherence tomography with fiber-based phase shifter
Optical Fibers and Sensors for Medical Diagnostics and Treatment Applications XVIII, 2018We present a balanced detection method for spectral domain optical coherence tomography (SD-OCT) using a fiberoptic phase shifter. SD-OCT systems typically use a single line scan camera to detect the spectrogram, and noninterfered signals are not excluded from the recorded signal. That limits dynamic range and reduces image quality.
